Prefix to OFW's chosen/bootpath

Hi Mitch,

On 1.75, looking at chosen/bootpath, as exposed by device-tree, shows
the path prefixed with /sd at d4280000/ .

Is that prefix stable? Does it refer to something (memory location)
that might change?

We parse this value in the init scripts that mount the boot partition,
and in the initramfs code that handles security and mounting the FS.
